`Application filed October 22, 1923. Serial No. 670,024.

ing to he a full, clear, and .exactdescription of the invention, such as will enable others skilled in the art to which it -appertains to ymake and use the same.

This invention'relates to a vision shield fora vehicle, such as the ordinary wind shield now commonly used on automobiles. lVith the high power lights now usedon automobiles it is well known that the driver is often blinded by the glare from the. lights of an approaching car. Y

It is an object of this invention to provide a wind shield of simple and efiicient construction vwhich will eliminate the blinding effect from the glare of the lights of an approaching machine.v

It is a further object ofthe inventionto provide a wind shieldcomprising'a laminaty cd sheet of transparent material and also to provide a wind shield shape of a prism It is also an object kof the invention to provide such a wind Shield which will` afford a plain transparent surface for the driver to see throughY when it is raining or snowing. j j

, It is a still further object of the invention to provide a wind shield, asabove'set forth, which is adjustable to various positions.

YThese and'other objects and advantages of the invention will be fully set forth in the following description made in. connection with the accompanying drawings rin which like reference characters refer to the same parts throughout the different'views, and in which,-

Fig. 1 is ak view in front elevation of the device, as seen from the rear of the wind shield; j

` Fig. 2 is an end view of the wind shield showing a different position of the same in dotted lines; and

Fig. 3 is a vertical section taken on the line 3 3 of Fig. 1, as indicated by the arrows in Figs. 2 and 3, but shown on an enlarged scale.

Referring to the drawings, a portion of preferably in the the cowl of an automobile body is illustrated as 1, from the sides of which rise the standards 2 serving to support the wind shield. Said' wind shield is shown as comprising a lower plane transparent section 3 which, if desired, may be swung about the axis ofv the pivots 4 and be clamped in position by the wing nuts 5.

In accordance with the present invention, an upper section of wind shield is provided comprising a transparent plate 6 preferably of glas-s, which normally, will occupy a substantially vertical position in line with the vertical position of the Shield section 3. The plate 6 has extending inwardly and downwardly from its upper edge a laminat-i ed transparent sheet 7 formed ofa plurality `of sheets 8 of' glass or other suitable transparent material arranged slightly spaced and in parallel relation. Another plate of glass or other trans-parent material 9 eX-- tends from the lower inner edge of the sheet 7 and adjacent the lower edge of the plate 6. The plates 6 and 9 and the laminated sheet 7 are held in rigid relation in a suitable metallicv frame 10 which extends about the edges of the glass plates and over the outersides of the end plates of glass or transparent material 11, which plates 11 extend across the ends of the plates 6, 8 and 9,r andare illustrated as parallel to each other.

vPlates 6 and 9 and the sheet 7 thus form a `hollow prism with transparent sides.

The shield comprising members 6, 7,'9, 10 and 11, is designated generally as A and the same is rotatable about a horizontal axis which is the axis of pivot members 12 extending through' the standards 2 and said shield A is held in any desired adjusted position by the wing nuts 13. The frame 10, at the lower outer edge of plate 6 has a downwardly and outwardly extending narrow strip 14 thereon adapted to form ay water shed from which the water ruiming down the plate' will drip. f I

With the shield section A in position shown in Figs. 2 and 3, the driver will look through the laminated sheet 7 vand the plate 6 in the usual mann-er. If a machine approaches with bright lights, the rays from said lights will pass through the vertical section 6 and will strike successively the inner surfaces of plates 8i. The plates 8 will be of highly polished material and a considerable portion of the rays will be reilected downwardly by the Vinner surfaces of the plates S. Only a portion ol the light, therefore, from the approaching maehine will pass through the laminated shet T so that the glare lrom said lights will be eliminated and the light will etteotiyely be dimmed. A suliieieut number ol plates 8 will be used to faire the desired dimming ellect, only two of the plates being shown in the emlanlinient ot the .invention illustrated. "the direction in which the rays `trom the approaching inaehine will be reflected from the inner suritaees oit' plates S will, ol" course. vary with the position ol said plates and said rays can be made to be rellreted down wardly onlo the road ahead ot the machine or any other direction by :uljustinir the section A on the pivot members 1Q. It will be noted that when the said section A is in the posh tion shown in dotted lines in Fig. Q. the plate 9 is below the plate (l. It it be raininpf. the water will strike against the plate (l and run down the sai e and drip otl ot the strip ll. The plate l) will. tlarelore.` be kept clean so that the driver willv have a clean transparent surface through whit-h to ohserve the road. The section A can be snrunnl further outward than shown luy the dette-:l lines in Fig. 2 so as to give a tree open space for the drirers vision, as is done with the swinging top section oi' the ordinary wind shield. The laminated sheet l' does not in any way interfere wth the drh/'ens rision.

From the above description it is seen that applicant has provided a siniple and ellicient structure ot adjustable wind shield having many ad `-antzin'es. The shield absolutely eliminates the objeetionable flare troni ap preachingr lights or 'from the son when the latter is near the horizon. The device possesses all the advantagijes ol? the ordinary plain adjustable wind shield section and, furthermore. as above deseibed. ilnrnishes a clean and clear driyei"s shield in the rain oijsnon'. The deriee ean he easily made and installed. either on ears already huilt or when the same are ori p inally creased. The device has been demonstrated in actual prat: tice and 'found to be very sncreilul and elilieient 'lor the purpose intended.

lt will. ot course. be understood. that rarions changes may be made in the torni. details, arrangement and proportionsl ol the parta without departing' 4trom the seope ot applicants invention. which. `afeiierally stated. consists in a devine capable oi carrying out the objects above stated. sueh as shown and described and set forth in the appended claims.

that is claimed is:

l. A vision shield tor an automobile comprising a triangular prism haring a trans parent ifi-ont side normally disposed in a vertical plane, a rear transparent laminated side normally extending at an acute angle downwardly from said vertical side, and a botten trai'isparent side extending substantially normally to said rear side, said prism being rotatable about an axis parallel, to one longitudinal edge and disposed substantially in the front side.

2. A vision wind shield for an automobile comprising a member formed ot a plurality of flat slightly spaced substantially parallel transparent sheets inclined at a considerable angle to the horizontal.

-l. A vision shield for a vehicle comprising` a transparent plate and a plurality o'l slightly space-d substantially parallel transparent .sheets extending at an inclination to the plane of said plate.

il. A vision shield tor a vehicle comprising a hollow prism having; transparent sides and its longitudinal axis extending substan tially transversely of the longitudinal eenter line of said vehicle. one ot the sides ot said prism being1r formed of a. plurality of slightly spaced transparent sheets.

A shield for a vehicle comprieinery a transparent: plate normally disposed substantially in a vertical plane and a member comprisiirer a plurality ot spaced substantially parallel transymrent plates extending` inwardly and angnlarly there-trom and in llxcd relation thereto.

(l. A wind shield for a vehicle haring a lower plane section normally in Vertical position and an upper section reyoluble about a horizontal axis comprising a normally vertical transparent plate. a` laminated transparent sheet extending rearwardly and downwardly from adjacent the top oit said plate and a transparent plate extending outwardly and downwardly trom the lower edge ot said sheet to the lower edge ot said lirst mentioned plate, said plates and sheet beingT held in rigid relation.A

T; The structure set 'lf'.ntl. in claim triangular parallel plates` extending;` the ends ot said plates and sheet.
